IMPROVEMENT IN FRUITJARS.

Specification forming part of Letters Patent No. 47,834, dated May 23, 1565; antedated December 6, 1864.

To all whom, it may concern.: Beit known that l, CHARLES G. IMLAY, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain Improvements in Fruit-J ars and other Vessels for Preserving Fruits or Similar Substances; and I do hereby declare that the followingis a full and exact description thereof, reference being had to the annexed drawings, and to the letters of reference marked thereon.

My objects are twofold- The rst is securely to lock the main or principal joint of the jar, the only joint when no aperture is used. For this I make three forms of my cap, a sheet-metal screw-cap, a sheet-metal or cast slotted cap, and a glass screw-cap, each-being iitted to corresponding Y parts of the jar.

Second, to make aseries o1 stoppers adapted to my uses of them.

In Figure'l, a is the jar; b, -a stopper with an aperture closedl by the india-rubber plug z. The joint between the glass stopper and the jar is made air-tight by the gasket d, which has no necessary contact with the metal cap c, the only use of the cap being to hold the stopper in firm contact with the jar by the screwthreads mutually made on the jar and cap.

Fig. 2 is another variety of my metal cap,

used 'for the same purpose as stated, the glass stopper being `locked to the jar by means of knobs or lugs, or short portions of screwthreads, operating in two or more inclined slots, l. A secondary variety of this cap is seen at Q x, in which case no glass stopper is used, but the gasket'is compressed directly by the cap.

In Fig. 4, c, at the left hand, exhibits the top of the cap of Fig. l, and to it are fitted the glass Stoppers of all the series, except ig. 3. l i

Fig. 3 is the same device as in Fig. l, made either with or without the cap and plug b and e, but the stopperl and capping-'screw edges are cast in one piece of glass;I and for the sake of brevity these Stoppers may be classed as two Varieties, those without aperture or apertures as are b a, b b, and b c, of which still others may be given, and those with one or `more apertures, as are the iigures b d, be, bf, b h, b z', b 7c, and b @and the uses of each are apparent to adepts in the art of preserving, some rising above the caps, some beingV below,

some excluding the air at the edges, others in the cup, and b w has two holes at thebase of the plug for the same purpose.

The uses and adaptation of my invention to fruits and other preserving is apparent to those skilled in the art to which it appe'rtains. I claiml. The use of the metal screw-cap c, for the.

purpose of locking any form or variety of glass Astopper upon a glass jar, as described. .Y 2. The glass stopper and cap b j, when fastjar in the mancned by screw-threads to the ner described.

3. A` metal cap, when by inclined. slots in the cap and by projections or lugs or portions of screw-threads on the neck of the j ar it locks a glass stopper to a glass jar, and the same Awhen no glass stopper is lused.

4. The use of the hollow tube-plug b k and.

(with two apertures at its base,) for locking the aperture inside of the jar, as de- -plug b x,

scribed.

5. All and each of the described and figured Stoppers, when used in combination with my locking-caps.
